The Couples Health CoOp Plus (CHC+) was adapted from the Couples Health CoOp (CHC)-an empowerment-based intervention developed for South African couples that addresses the syndemic of alcohol and other drug (AOD) use, violence, and HIV risk. It is grounded in Social Cognitive Theory and promoted prevention strategies that addressed the relational context of equality in which sexual risk takes place. The Couples Health CoOp (CHC) has demonstrated efficacy in increasing condom use, improving relationship norms, decreasing heavy alcohol use among men, and decreasing HIV incidence among women. Long-term benefits of the Couples Health CoOp (CHC) have been explored including women reporting less fighting with their partner and men reporting being more faithful and loving. As part of this current study (Aim 1), the behavioral Couples Health CoOp (CHC) was adapted to include biomedical HIV strategies antiretroviral therapy (ART)/pre-exposure prophylaxis (PrEP) and updated materials. Formative qualitative work with a Community Collaborative Board (CCB) and a Peer Advisory Board (PAB) guided the adaptation and updating of the Couples Health CoOp Plus (CHC+) intervention. The Couples Health CoOp Plus (CHC+) is a 2-module workshop delivered over two days and contains didactic and experiential lessons on alcohol and other drug (AOD) use, a status-neutral approach to the prevention and management of HIV, sexual and reproductive health (SRH), relationship norms, violence, and tools to improve communication.
Formative findings regarding clinic-level stigma and discrimination showed that stigma reduction training provided in communities surrounding healthcare clinics may reduce stigmatizing behaviors and attitudes that are enacted by family, friends, and other community members toward those seeking healthcare. The stigma reduction survey and workshop were developed and adapted as part of Aim 1 formative activities.
The study enrolled approximately 20 couples in each of the 24 communities in and around Cape Town, South Africa. Communities surrounding healthcare clinics were paired according to community demographic and socioeconomic factors and randomized to one of four arms:
1. stigma awareness and education workshop (community) and HIV testing services (HTS)/antiretroviral therapy (ART)/pre-exposure prophylaxis (PrEP) (couple);
2. stigma awareness and education workshop (community), and HIV testing services (HTS)/antiretroviral therapy (ART)/pre-exposure prophylaxis (PrEP) with Couples Health CoOp Plus (CHC+) (couple);
3. no stigma awareness and education workshop (community) and HIV testing services (HTS)/antiretroviral therapy (ART)/pre-exposure prophylaxis (PrEP) (couple);
4. no stigma awareness and education workshop (community), and HIV testing services (HTS)/antiretroviral therapy (ART)/pre-exposure prophylaxis (PrEP) with Couples Health CoOp Plus (CHC+) (couple).
As noted, couples in communities that were not assigned to receive the CHC+ intervention received HIV testing services (HTS), including provision of antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) as part of standard of care.
HIV, alcohol and other drug (AOD), and pregnancy testing was conducted at baseline and at 3- and 6-month follow-up.
Assessment of community stigma occurred at baseline with all 24 communities and the stigma awareness and education workshop occurred in only those randomized to it. The follow-up occurred within all communities at 4- and 8-months post-baseline.
